public class DataStatistics
extends ResultObjectAdapter

This class encapsulates some very simple statistics about the given attributes. These are the ranges of the attributes and the average or mode values for numerical or nominal attributes respectively. This information is automatically calculated and displayed by the graphical user interface of RapidMiner. Since they cannot be displayed with the command line version of RapidMiner the operator DataStatisticsOperator can be used as a workaround in cases where the graphical user interface cannot be used.
